Privacy coins are cryptocurrencies designed to provide users with enhanced privacy and anonymity for their transactions. Unlike Bitcoin and many other cryptocurrencies, where transactions are recorded on a public ledger and can be traced back to the users' wallet addresses, privacy coins use various cryptographic techniques to obscure the transaction details. This includes hiding the identity of the sender and receiver, as well as the amount being transferred.

Key technologies used by privacy coins include stealth addresses (creating one-time addresses for each transaction), ring signatures (mixing a user's transaction details with others to obscure the source), and zero-knowledge proofs (allowing transactions to be verified without revealing any details about the transaction itself). Examples of privacy coins include Monero (XMR), Zcash (ZEC), and Dash (DASH), each offering different approaches and levels of privacy. Privacy coins address the demand for greater personal and financial privacy in the digital age but also face scrutiny from regulators concerned about their potential use for illicit activities. The use of privacy coins is banned in some jurisdictions, including Japan.
